An innovative losses model for efficiency map fitting of vaneless and variable vaned radial turbines extrapolating towards extreme off-design conditions

Serrano, J.R.; Arnau Martínez, Francisco José; García-Cuevas González, Luis Miguel; Inhestern, Lukas Benjamin (Elsevier, 2019-08-01)

[EN] Pulsating flow in automotive turbocharger turbines makes it necessary to know performance characteristics in difficult to measure off-design conditions. Physically based extrapolation models can be used to extrapolate ...
Radial turbine performance measurement under extreme off-design Conditions

Serrano, J.R.; Tiseira, Andrés Omar; García-Cuevas González, Luis Miguel; Inhestern, Lukas Benjamin; Tartoussi, H. (Elsevier, 2017)

[EN] During automotive urban driving conditions and future homologation cycles, automotive radial turbines experience transient conditions, whereby the same operate at very high blade speed ratios and, thus, at very low ...
Turbocharger turbine rotor tip leakage loss and mass flow model valid up to extreme off-design conditions with high blade to jet speed ratio

Serrano, J.R.; Navarro, Roberto; García-Cuevas González, Luis Miguel; Inhestern, Lukas Benjamin (Elsevier, 2018)

[EN] Due to the power consumption restriction of the turbocharger compressor, common turbine maps are rather narrow. To extrapolate them, reliable physical submodels are needed that are valid for broad ranges. Plenty of ...
